What is the best and most reliable way legally to stop a neighbor and their kids from tres

Resolved Question:

What is the best and most reliable way legally to stop a neighbor and their kids from tresspassing on my front yard more than one time? Can I send them a letter to request this action stop? They do this tresspassing more boldly when we are away. We have an alarm surveilance system that alerted us to the issue.

You could start with a letter asking that they refrain from coming onto your property. However, you can be more aggressive and file trespassing charges against them and get a court order stopping them from coming onto your land.

In regards XXXXX XXXXX letter: Should I send it certified with return receipt? Should I send a copy to the local police?

In regards XXXXX XXXXX trespassing charges: Is this more a civil matter or criminal. I have photos of the behavior. They occurred on two separate days. I am concerned it will continue if I do nothing. Yet, I want to temper my approach too as we have to live next door to these people. I am concerned the man could lose his cool.
